Question

Controller

function __construct() 
{ 
    parent::__construct(); 
    $this->load->model("staffmodel","staff"); 
} 

function index() 
{ 
    $data['staff'] = $this->staff->getAll(); 
    $this->load->view("staff/index",$data); 
} 

function create() 
{ 
    if(@$_POST['create_staff']) 
    { 
     $data = $this->input->post('staff'); 
     $this->staff->add($data); 
     $this->session->set_flashdata('message',"staff created successfully"); 
     redirect("staff"); 
    } 
    $this->load->view("staff/create"); 
} 

function edit() 
{ 
    $id = $this->uri->segment(3); 
    $post = $this->staff->getById($id); 
    if(!$post) 
    { 
     redirect("staff"); 
    } 

    if(@$_POST['update_staff']) 
    { 
     $postdata = $_POST['staff']; 
     $this->staff->update($postdata,$id); 
     $this->session->set_flashdata('message',"Staff updated successfully"); 
     redirect("staff"); 
    } 

    $data['staff'] = $post; 
    $this->load->view("staff/edit",$data); 
} 

function delete() 
{ 
    $id = $this->uri->segment(3); 
    $this->staff->delete($id); 
    $this->session->set_flashdata('message',"Staff deleted successfully"); 
    redirect("staff"); 
} 

Modell

var $table = "staff"; 
function __construct() 
{ 
    parent::__construct(); 
} 

function getAll() 
{ 
    $q = $this->db->get($this->table); 
    if($q->num_rows() > 0) 
    { 
     return $q->result(); 
    } 
    return array(); 
} 

function add($data) 
{ 
    $this->db->insert($this->table,$data); 
} 

function update($data,$id) 
{ 
    $this->db->where("id",$id); 
    $this->db->update($this->table,$data); 
} 

function delete($id) 
{ 
    $this->db->where("id",$id); 
    $this->db->delete($this->table); 
} 

function getById($id) 
{ 
    $this->db->where("id",$id); 
    $q = $this->db->get($this->table); 
    if($q->num_rows() > 0) 
    { 
     return $q->row(); 
    } 
    return false; 
} 

ich kann einfach nicht herausfinden, was dieser Fehler zeigt ......... .................................................. ...................................... Ich kann keinen Weg finden, diesen Fehler zu beheben Bitte helfen Sie mir

Answer 1

Ändern Sie diese

$postdata = $_POST['staff']; 

dieser

$postdata = $_POST; 

Es funktioniert. Da Sie das Array staff direkt an diese Variable senden, wird standardmäßig 0 als Schlüssel verwendet.

Answer 2

Syntaxfehler: Entfernen var in der ersten Zeile

$table = "staff";
